Graphtec plotter - "Can't Open Port" error

That's A Wrap

New Member
Hey guys, so I got it connected thanks to everyone's help!

But now I have another problem, sometimes the cutter will say Error 1: Instructions not recognized. Other times it will connect to pc but only when its on load media screen or menu-> interface -> RS232 page.

Any help is appreciated!

Been here a while..
Make sure the serial settings on the computer match those on the plotter. Sounds like something is too fast and is filling the buffer without the plotter telling the pc to stop sending data
